Coherent State Path Integrals in the Weyl Representation [PDF]

open access: yes, 2006
We construct a representation of the coherent state path integral using the Weyl symbol of the Hamiltonian operator. This representation is very different from the usual path integral forms suggested by Klauder and Skagerstan in \cite{Klau85}, which ...

On mutually independent hamiltonian paths

open access: yesApplied Mathematics Letters, 2006
Two Hamiltonian paths \(P_1=\langle v_1,v_2,\dots,v_n\rangle\) and \(P_2=\langle u_1,u_2,\dots,u_n\rangle\) of an \(n\)-vertex graph \(G\) are independent if \(u_1=v_1\), \(u_n=v_n\), and \(u_i\neq v_i\) for ...

Decomposing the Complete Graph Into Hamiltonian Paths (Cycles) and 3-Stars

open access: yesDiscussiones Mathematicae Graph Theory, 2020
Let H be a graph. A decomposition of H is a set of edge-disjoint subgraphs of H whose union is H. A Hamiltonian path (respectively, cycle) of H is a path (respectively, cycle) that contains every vertex of H exactly once.

Renormalized Path Integral in Quantum Mechanics [PDF]

open access: yes, 1996
We obtain direct, finite, descriptions of a renormalized quantum mechanical system with no reference to ultraviolet cutoffs and running coupling constants, in both the Hamiltonian and path integral pictures.

Problems on Shortest k-Node Cycles and Paths

open access: yesКібернетика та комп'ютерні технології, 2021
The paper is devoted to the construction of mathematical models for problems on the shortest cycles and paths, that pass through a given number of nodes of a directed graph.

Solving the Hamiltonian path problem with a light-based computer [PDF]

open access: yesNatural Computing, 2007
In this paper we propose a special computational device which uses light rays for solving the Hamiltonian path problem on a directed graph. The device has a graph-like representation and the light is traversing it by following the routes given by the ...

Energy Conditions for Hamiltonian and Traceable Graphs

open access: yesUniversal Journal of Mathematics and Applications, 2019
A graph is called Hamiltonian (resp. traceable) if the graph has a Hamiltonian cycle (resp. path), a cycle (resp. path) containing all the vertices of the graph. The energy of a graph is defined as the sum of the absolute values of the eigenvalues of the

Path Integral Monte Carlo Approach to the U(1) Lattice Gauge Theory in (2+1) Dimensions [PDF]

open access: yes, 2002
Path Integral Monte Carlo simulations have been performed for U(1) lattice gauge theory in (2+1) dimensions on anisotropic lattices. We extractthe static quark potential, the string tension and the low-lying "glueball" spectrum.The Euclidean string ...
